Appendix B - Thirteen OSHA-Regulated Carcinogens

Without establishing PELs, OSHA promulgated standards in 1974 to regulate the industrial use of 13 chemicals identified as potential occupational carcinogens.

  • 2-Acetylaminofluorene
  • 4-Aminodiphenyl
  • Benzidine
  • bis-Chloromethyl ether
  • 3,3'-Dichlorobenzidine
  • 4-Dimethylaminoazobenzene
  • Ethyleneimine
  • Methyl chloromethyl ether
  • alpha-Naphthylamine
  • beta-Naphthylamine
  • 4-Nitrobiphenyl
  • N-Nitrosodimethylamine
  • beta-Propiolactone

Exposures of workers to these 13 chemicals are to be controlled through the required use of engineering controls, work practices, and personal protective equipment, including respirators. See 29 CFR 1910.1003-1910.1016 for specific details of these requirements.

Respirator selections in the Pocket Guide are based on NIOSH policy, which considers the 13 chemicals to be potential occupational carcinogens.
